I have seen that coupon one too. But what I have seen a ton of times is this malware (don't remember the name) that will show up as a full screen advertisement of a program that you need to pay to remove the screen in question. Problem is if you try safe mode it reboots on you the second you log in (fun times!). You either have to get into another user account or access the admin account and perform a manual removal.

Seen a load of this coming through DomaIQ, where you get paid if someone installs your program, you get a flash player update pop up, which in turn downloads flash_player_v_.123.exe which when run install all manner of PUP`s (coupon thingie, Yontoo, etc). Seems a lot are being pushed through the ads

i would say yontoo and coupon printer are the most common ones i see, mostly because people A) are cheap and always look for coupons without ever thinking, why should i have to install software to print them. and B) they never deselect things they dont want to install.
